Ernest Beutler

Ernest Beutler (September 30, 1928 – October 5, 2008) was a German-born American hematologist and biomedical scientist. He made important discoveries about the causes of a number of diseases, including anemias, Gaucher disease, disorders of iron metabolism and Tay–Sachs disease. He was also among the first scientists to identify X-inactivation as the genetic basis of tissue mosaicism in female mammals, and pioneered a number of medical treatments, including bone marrow transplantation techniques. Beutler was the Chairman of Medicine at the City of Hope Medical Center in Duarte, CA from 1959 until 1979 and served as a Professor, then Chairman, of the Department of Molecular and Experimental Medicine at The Scripps Research Institute in La Jolla, California from 1979 until 2008.
